STILLWATER, Okla. - The No. 24 Iowa State women's basketball team was held scoreless for the first 8 minutes of the second half, eventually suffering its worst loss in more than a year with a 71-42 throttling at the hands of No. 17 Oklahoma State on Sunday afternoon.
The Cowgirls scored the first 20 points of the second half and outscored Iowa State 40-21 after intermission for their third straight win.
"Obviously we just got totally beat up, spanked, whatever term you want to use," said ISU coach Bill Fennelly. "Oklahoma State was great and (this was) by far the worst we've played all year."
Five players scored in double figures for Oklahoma State (14-2, 3-2), led by Liz Donohue's 18 points and eight rebounds.
Hallie Christofferson had a double-double of 14 points and 10 rebounds to lead the Cyclones (13-3, 4-2), whose last 29-point loss came in last season's Big 12 Conference opener at Oklahoma on Jan. 4, 2012.
"Hallie Christofferson was the only person that showed up this game, and when you do that against a top-20 team on the road you're going to get beat bad," Fennelly added. "OSU was great, played great, was very physical with us and we didn't handle it well.
"They were the far better team today and I'm certainly disappointed we didn't give a better effort."
The Cowgirls led 31-21 at the half before scoring the next 20 points out of the break. ISU finally ended the drought with a pair of Chelsea Poppens free throws at the 11:54.
The Cyclones shot just 16-for-52 (31 percent) from the field and 5-of-24 (21 percent) from 3-point range. Poppens finished with nine points, and Anna Prins had eight points and eight boards.
"Our defense has been pretty solid all year but when you're not making baskets, over time it's going to kill you," said Fennelly.
Oklahoma State shot 50 percent from the field and 82 percent at the free-throw line. Tiffany Bias and Kendra Suttles had 12 points apiece while Toni Young and Brittney Martin both added 10 for the Cowgirls.
It only gets rougher for the Cyclones, who host top-ranked Baylor on Wednesday night at 7 p.m. inside Hilton Coliseum. It will be ISU's second game against the Lady Bears in their last five outings - the first was a 28-point loss in Waco, Texas.
